i stumbled upon this website today upon my travels...
from what i've read of it.. it removes harmful things from the air Such as Germs, Mold Spores and Odors....
Anyone heard of these Types of Bulb before?

"Mechanism of Photocatalysis
When our next generation nano photocatalyst absorbs energy from sunlight or an illuminated light source (fluorescent lamps), it will produce pairs of electrons and holes. The electron of the photocatalyst valence band becomes excited when illuminated by light. The excess energy of this excited electron promotes the electron to the conduction band of the photocatalyst thus creating the negative-electron (e-) and positive-hole (h+) pair. This stage is referred as the semiconductor's 'photo-excitation' state. The energy difference between the valence band and the conduction band is known as the 'Band Gap'. Wavelength of the light necessary for photo-excitation is:
1240 (Planck's constant, h) / 3.2 ev (band gap energy) = 388 nm and higher."
"The positive-hole of the photocatalyst breaks apart water molecules to form hydrogen gas and hydroxyl radicals. The negative-electron reacts with oxygen molecules to form superoxide anions. The superoxide anions and hydroxyl free radicals oxidize the germs, chemical contaminants and odors into harmless carbon dioxide and water. This cycle continues indefinitely as long as light is available and the catalyst does not become depleted."

if i had the room i would totally hook a few up.
but it would still be pretty neat to have a few if you have the money and space xD
